Great idea to lengthen the Sverige-type CDS! However, if I may add my fifty öre to the design: personally, I'd raise the clearance of the amidships (no.2) turret to avoid excessive blast on the deck fittings. This can be done simply by raising the turret base to the same height as Tate forward one. Also the MG:s you've positioned at either forward tip of the aft superstructure will be close to useless in their very exposed sites. What I'd do is remove them, add a clinker extension and put more boats on that. With increased size also comes larger crews! Remember that the Sverige-ships did have up to eight ships's boats; you only have four...

Though, I don't know much about ships of this era, I admire your skills and especially top views; we always want to see those :)

Thank you! I'll see what I can do about the issues you mentioned.

Here's another pair. The first one is a small battlecruiser loosely based of Soviet heavy cruiser projects I've read about(and I looked a on the Kronstadt class battlecruiser for the superstructure layout). The other is a light cruiser to keep her company.

I like these very much. They have that Soviet/Italian look, but could easily pass for another nation's vessels.
Keep having these great ideas!
